Hi, I have a board based on the Lite5200b, except that the serial console is on
PSC4 instead of PSC1.
Using the a custom U-boot (1.2.0) and kernel 2.6.21 (compiled for powerpc), I
managed to get U-boot to output on the console on PSC4, but the kernel
does not.
I had just modified lite5200b.dts in some points:
1- My memory is 128Mb
2- I don't need eth,mdio,ata so I had commented
3- Enable PSC4
4- Added the chosen node:
chosen {
linux,stdout-path = "/[EMAIL PROTECTED]/[EMAIL PROTECTED]";
bootargs = "console=ttyPSC4,115200";
};
Debugging my board i notified that u-boot read & modify the device tree blob
adding the chosen node:
chosen{
name = "chosen";
bootargs = "console=ttyPSC3";
linux,platform = <600>;
linux,initrd-start = <7e2e000>;
linux,initrd-end = <7f0fbf2>;
linux,stdout-path = "/[EMAIL PROTECTED]/[EMAIL PROTECTED]";
};
I follow step by step the kernel start procedure.. and I notify that in
setup_arch funtion is called find_legacy_serial_ports, but when is done
if(legacy_serial_console >= 0)
legacy_serial_console is equal to -1.
However, it is not sufficient. What am I missing?
Thank you!
